TRAP AND OUTLET CONSTRUCTION FOR BATH-TUBS.

Specification of Letters Patent.

Patented Jan. 5, 1909.

App1ication filed June 15, 1908. Serial No. 438,452.

T 0 all whom it may concern:

Be it known that I, JOHN F. EICHENLAUB, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented certain new and useful Improvements in Trap and Outlet(onstruction for Bath-Tubs, of which the following is a specification.

My invention relates to the improvement of trap and outlet constructionfor bath tulcs and the objects of my invention are to provide animproved overflow, waste and trap construction for bath tubs and tocombine the same with means for preventing the freezing of the water inthe trap or outlet pipes leading thereto to so construct my improvedtrap and parts connected therewith as to admit of the trap being readilyaccessible for the purpose of cleaning or repairs and to produce otherimprovements the details of which will he more fully pointed outhereinafter. These objects I accomplish in the man ner illustrated inthe accompanying drawing, in which: 7

Figure 1 is a sectional view of a portion of a bath tub showing partlyin section and partly in elevation my improvements connected therewith,and, Fig. 2 is a transverse section on line rc9c of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

1 represents a suitable form of bath tub, from the lower side of whichleads downward and thence outward the usual waste pipe 2.

3 represents the overflow opening of the bath tub and 4 the overflowpipe which leads outward and thence downward from said opening 3.

5 represents avertical cylindrical casing section, with which is formeda horizontal pipe arm 6 which extends partially within and partiallywithout the casing 5. This pipe arm 6 has its inwardly extending portionterminating in a vertical T-head 6 within the central portion of thecasing 5, while the outwardly extending ortion 6 of the pipe 6 is connected wit the horizontal portion of the waste pipe 2 by suitable waterand gas-tight connections 7.

The lower end of the vertical portion of the overflow pipe 4 fits withinthe upper end of the T-head 6 the latter being provided with an internalrubber gasket 8 which aids in forming a water and gas-tight connectionof said overflow pipe and T-head. The lower end of the T-head 6 hasscrewed into con nection therewith an oblique pipe section or coupling9, the lower end of which has a threaded connection with the upper endof one of the vertical members 10 of a substantially U-shaped trap 10.The remaining vertical member of the trap which is indicated at 10 hasits upper open end at substantially the same level as the upper end ofthe member 10.

The trap thus produced and caused to depend from the coupling section 9,is contained within a vertical cylindrical casing section 11 whichextending through an opening 12 in a building floor 13, has its upperend portion 1 closely fitting within the ower end of the uppercylindrical casing 5, the connection between said upper and lower casingsections being made water and gas tight through the medium of a rubbergasket 14 which is embedded in an inner side recess of the lowerportionof the casing section 5.

As shown in the drawing, the lower portion of the trap body extends to apoint slightly below the floor 13 and to a point immediately above thelower end of the casing section 11. The lower end of this casing section11 is screwed, as shown, into the internally threaded boss of a buildingwaste pipe 15 which runs beneath the floor 13 and which leads to asewer. In the construction of the waste pi e section 15, the same isformed on one si e of its opening 15*, through which communication iseffected with the interior of the casin section 11 with an inwardlyprojecting and ownwardly curved lip 15".

The upper end of the casing section 5 is closed by a cap 16 which isformed with a central top opening through which the pi e 4 passes. willbe observed that the united sections 5 and 11 form a cylindrical body,the greater portion of which rojects above the floor of the room and t1e cylindrical body thus formed provides a housing for containing achamber for the trap and the pipe connections therewith.

It will readily be understood that water from the bottom or waste outlet1 of the bath tub, will follow the line of full line arrows to the trapand from the upper end of the trap member 1O the water will passdownward to the sewer connection or waste pipe 15. It will also beunderstood that water which passes from the overflow open- From theconstruction describe it will pass downward to the pipe 15.

ing 3 of the tub into the pipe 4, will likewise be directed into thetrap.

Owing to the fact that water is constantly standing in the trap body,considerable difficulty has been experienced from the freezing of waterin the trap and in the pipes connected therewith. By the constructionwhich I have described, it will be understood that the warm sewer airwhich is always present in sewer connections, such as the pi )e 15, willbe permitted to follow the line of dotted arrows and rise within thecasing body formed by the sections 5 and 11 and as the heated air fromthe sewer becomes cool, it It will thus be seen that a circulation ofwarm air will be maintained within the housing which surrounds the trapand the water in the trap will thereby be prevented from freezing. Inorder to better direct the warm air from a sewer into the trap housing,I have provided the projecting or flaring lip 15 which will assist indirecting the air upward.

It will be observed that the housing being formed in detachablesections, the same may be, readily separated when desired, for the,

purpose of cleaning or repairing the trap or its connections.

By the construction shown and described, it will be seen that the trapand its immediate connections will be entirely hidden from view and thatthe housing which surrounds said trap and connections, may be made topresent a neat and attractive appearance by suitably plating orornamenting the same.

What I claim, is:

In a Waste, overflow and trap construction for bath tubs, thecombination with a tub, a trap, and waste and overflow pipes leading tosaid trap from said tub, of a casing inclosing said trap and the wasteand overflow connections therewith, said casing being air and watertight, and a sewer connection below the trap connected with the lowerend of said casing.

In testimony whereof I aHiX my signature in presence of two witnesses.

JOHN F. EICHENLAUB.
